Anthropogenic Effects on Eel Migrations in Streams of Antalya Basin of Turkey

In consideration of the scientific records and current observations obtained from the early 1980s until today in order to investigate the eel migrations in the main streams of Antalya Gulf, we here reviewed the changes in the elvers arrival into the streams, how habitats have changed until today, and the anthropogenic pressures on habitats. Elvers arrivals into the streams have been significantly affected by habitat destructions such as pollution, an excessive reduction in water level, sand removal and streambed arrangement; mechanical barriers such as regulators and dams; tourism intended arrangement of estuaries, and habitat losses caused by anthropogenic activities such as motor boats and scoop fishing nets. On the other hand, the tragic decrease in adult eel populations has been considered able to result from factors such as reduced flow rate, streambed destruction, overfishing and global declines in stocks
